た熱伝導防止一体はりに関するものである。[Detailed Description of the Invention] The present invention relates to an integral beam for preventing heat conduction, in which a fiber-reinforced heat insulating material is sandwiched between two beam components at the middle of the cross section of the beam to form an integral structure.
従来、建築および車両の構体構成に使用する金属製はり
は、はりの一面に外板を、他の一面に内張りを取り付け
ており、はりとはり間の外板と内張りの内部に断熱材を
そう人している。Conventionally, metal beams used in construction and vehicle structures have an outer panel on one side and an inner lining on the other, and insulation material is installed inside the outer panel and lining between the beams. There are people.
しかし、構体構成に使用する金属製はりは室内と室外と
の間の熱伝導媒体となり、断熱効果を低下させる欠点が
ある。However, the metal beams used in the construction of the structure serve as a heat conduction medium between indoors and outdoors, which has the disadvantage of reducing the heat insulation effect.
また、金属製はりを２個の構成要素に分け、その間に断
熱材を接着によらないでサンドイッチした場合は熱伝導

はりより低くなる欠点を有する。In addition, if a metal beam is divided into two components and a heat insulating material is sandwiched between them without adhesive, heat conduction can be prevented, but the bending stiffness of the metal beam divided into two components , has the disadvantage of being lower than a one-piece metal beam that is not divided into two components.
本考案は上記欠点を除去するもので、建築および車両の
